This invention relates to fans and more particularly to a swinging fan of the multiple type adaptedto be suspended from a ceiling or other overhead support and have osci1- latory motionimparted to it sothat air in a room willfb'e kept in motion. I f

One object of the invention is to so mount the air agitators that they will be disposed in cable and means for imparting motion thereto first inonefdirection and then ina' reverse di-' rection. .7

Another object of the invention to provide an improved guide for the actuating cable, including a pulley rotatablymounted and slidable verticallyiso that'there will be no danger of the cable moving outjof proper engagement with the pulley. I,

Another object of the invention is to firmly connect the shank of a fan blade with a cross. head forming part-ofthe. agitator and to so mount the blade that it may befvertically ad 'justed and thereby disposed in pro-per spaced relation to the ceiling ofa room.

' The inventiontis illustrated in the accompanying drawing wherein f 3 Figure 1 is a view'showing the improved fan in side elevation; Fig. 2 is a view' showing the operating means for the fan in end elevation V Fig. 3 is an enlarged View of one of the air agitators showing thesame in elevation; Fig. 4 is a viewshowing the agitatorpartially in side elevation and partially in section, and Y Fig. 5 is a fragmentary sectional view taken on the line 5 75 of Fig.4. i I The improved fan is to be suspended from ect, of the invention is to proagitators including a substantially endless a ceiling or other overhead support and in- I eludes end hangers 1 and 2 and intermediate hangers 3 which carry air agitators, indicated 1n general by the numeral 4. Each of the hangers 3 is provided with depending'transversely spacedarms 5 having bearings (Tat 7 their lowerends to receive a shaft 7 about which is disposed a tubular crosshea'd- 8; The crosshead8' carries anti-friction rollers 9 so that it may turn'freely upon the shaft 7 and is formed with an upwardly extending internally-threaded socket 10 and a depend- 'ing neck 11." The fan blade 12 which is preferably formed of strong sheet metal has been shown sem1-c1rcular in shape and is carried by a U-shaped shank 13 formed from a metal 7 rod bent intermediate its length and having the oined lower ends of its arms 14 disposed about a fastener 15 between the blade 12' and a washer16. 5 Bythis' arrangement the blade may": be slid longitudinally uponzthe shank to dispose it the desired distance from the ceilingof a room and it will be frictionally'held'in a set position. Theupper ends of the arms 14- are disposed againsta fiat survface of the neck '11 and. are firmlyheld thereto bya cross strip or plate 17' and securing bolt I 18. this'arrangeine'nt the shank will be firmly secured tothe 'crosshead butmay be easily detached therefrom when necessary. Theh'andle 19 of the fanco'nsists' of a rod t 0 o'rjpipe'of a suitable length WlllClLllELS its lower end'portion threaded andscrewed into the socket;10'and its' upper end portion also threaded and carrying a nut 20 constituting a support for a suit-ablenumber of lead or other metal disks 21. Since the nut or support 20 V is threaded upon-the handle it may be adjusted thereon in order to accommodate the desired number of Weights or disks 21 with-. out danger of them slipping'olf the handle. It will be. obvious that, ifdesired, a retainer nut may bethre'aded upon the handle above the weights and firmly hold them in placeQ The hanger 1 is somewhat similar to the hangers 3 but is provided withonly one arm, the lower end of'which'isbent to form aside extension 22 to engage and, support the lower {end of a circular r od orpin 23., This rod carries a roller 24 which is of a concaved' formation andis rotatably'jand slidably mounted shaft 34 is rotated through the medium of a belt 36 leading from a motor or other source of power and trained about the pulley 37 rotary motion will be imparted-to thecrank shaft 273. The crank arm 29 of the crank shaft is connected with the handle of. the adjacent agitator by a shortrope or cable: 38 and a long rope or cable 39 is secured to the crank arm 28-and after being trained about the guide pulley 2tissecured to the handle of the agitator next to the hanger 1. Rods or cables L0 extend between and are secured; to the handles of the agitators in a tightened condition, andit will be-readily seen that when the crank shaft is rotated: its arms willalternately exert a pulling action upon the cables.- 38' and 39. Therefore, the agitators will be swung. and oscillated first towards the hanger l and then toward the hanger 2i andas they swing the blades: 12 will cause the air in a room to be thoroughly agitated and prevented from becoming stagnant. It will, of c'ourse,.be understood. that additional agitators and. hangers for the same may be provided if the fan is to be installed in: a very large room: or only one employed if the fan is used. in a small roo1n.. As the crank shaft turns, the cable will receive a certain amount of vertical swinging movement due to the movement of the crank arm 28 but since the guide pulley is sl'idable upon its red 23 there will be no danger of this cable slipping out of proper engagement with the guide pulley.v If it is found that the blades are not properly spaced from the ceiling, they may be easily adjusted upon their shanks and if it is found that the fans do not swing properly weights may be added to or removed from the handles until the upper and lower portions of the fans are counter-balanced.

Having thus described the invention, I claim:

1. A fan system comprising a rotatably mounted crank shaft having crank arms extending in opposite directions, a guide pulley rotatably mounted and slidable vertically,

hangers between said guide pulley and crank shaft, fans having vertically disposed handles pivotally connected with said hangers and blades at their lower ends, cables con necting the upper end portions of said handles, a cable connected with the upper end portion of the handles of fan adjacent the pulley and trained about said pulley and secured to one crank arm of the crank shaft, and a cable connecting the other crank armof the crank shaft with the upper end portion of the handle of a fan adjacent thecrank shaft.

2. A fan system comprising end hangers and an intermediate hanger between the end hangers, a horizontal crank shaft rotatably supported by one end hanger, a pulley rotatablysupported by the; other end hanger and slidable vertically thereon, an agitator having a vertically disposed handle pivotedintermediate its length to the intermediate hanger and a blade at the lower end of the handle, a flexible member connecting the upper end portion ofsaidhandle'wrth a crank arm of said crank shaft, and a second flexible member connected with the upper-endporti'on of said handle and trained about said pulley and. connected with another crank arm of the crank shaft.

A fan system compri one having depending bearing arms and the other a verticallyextending rod, a pulley rotatably mounted upon said rod and slidable vertically thereon, a crank shaft rotatably supported by said bearing arms and having crank arms extendingin opposite directions, an agitator between said hangers having a vertically disposed handle pivotally mounted between its upper and lowerends and a blade carried by the lower end of the handle, flexible means connecting said handle with one crank arm, and flexible means connected with theother' crank arm and trained about said pulley and connected with the handle:

t. A fan system comprising end hangers, one having depending bearing arms and the other a vertically extending rod, a pulley rotatably' and slid-ably mounted upon said rod, a crank shaft rotatably supported by said sing end hangers,

-5. A fan system comprising a-han-ger having spaced depending bearing arms,-an agitator including a crosshcad rockably mounted between the bearing arms of said hanger and having an upstanding socket anda depending arm intermediate its length, a handle carried by said socket, a U-shaped shank having the upper ends of its arms secured against the.

depending arm of said crosshead, ablade fitted agalnst said shank and having a as tener passing between the arms thereof to connect the blade with the shank and permit adjustment of the blade longitudinally thereon, and actuating means connected with said handle and adapted to impart swinging 1 movement tothe fan. In testimony whereof I afiix my si natnre.
